overview the kinetis mcu portfolio consists of multiple pin-, peripheral- and software-compatible mcu families based on the arm ? cortex?-m4 core. families are built from innovative 90 nm thin-film storage (tfs) flash technology with unique flexmemory (eeprom) capability, and offer industry- leading low power and mixed signal analog integration. the k40 mcu family adds full-speed usb 2.0 on-the-go with device charger detect capability and a flexible, low-power segment lcd controller with support for up to 320 segments. devices start from 64 kb of flash in 64 lqfn packages extending up to 512 kb in a 144 mapbga package with a rich suite of analog, communication, timing and control peripherals. 32-bit mcus low-power mcus with usb and lcd kinetis k40 family target applications ? gps receivers ? blood glucose meters ? bike computers ? currency counters kinetis k40 family standard optional kinetis k40 family cyclic redundancy check (crc) xtrinsic low-power touch-sensing interface segment lcd controller timers system memories communication interface sh mi clocks internal and external watchdogs memory protection unit (mpu) dma low-leakage wake-up unit phase-locked loop frequency- locked loop low/high- frequency oscillators internal reference clocks carrier modulator transmitter periodic interrupt timers independent real-time clock (rtc) security and integrity analog core interrupt controller debug interfaces dsp arm ? cortex?-m4 72/100 mhz 16 -bit adc pga analog comparator 6-bit dac 12-bit dac voltage reference flextimer programmable delay block low-power timer program flash (64 to 512 kb) flexmemory (32 to 256 kb) (2 to 4 kb ee) serial programming interface (ezport) sram (16 to 128 kb) external bus interface (flexbus) gpio i 2 c uart (iso 7816) spi can i 2 s secure digital host controller (sdhc) u sb on-the-go (ls/fs) u sb voltage regulator usb device charger detect (dcd)
